python實現(xiàn)簡單點對點（p2p）聊天

更新時間：2017年09月13日 08:34:37 作者：Lockeyi

這篇文章主要為大家詳細介紹了python實現(xiàn)簡單點對點p2p聊天，具有一定的參考價值，感興趣的小伙伴們可以參考一下

點對點聊天首先是基于多線程的網(wǎng)絡編程，其次就是將每一個連接都保存為一個具有獨一屬性的對象并添加到連接列表中，對于每一個連接對象發(fā)送過來的信息必須要包含主要的三項內容（from,to,messages），這樣當信息發(fā)送到服務器之后服務器根據(jù)to的連接對象遍歷連接列表找到目標對象將信息發(fā)送給目標，目標拿到信息后就知道是誰發(fā)過來的，然后根據(jù)id號碼進行回復。此實現(xiàn)將會繼續(xù)完善，后續(xù)新加功能將會在我個人github主頁展現(xiàn)

服務器端實現(xiàn)：
